DSO time

Just finished my meeting. Now I am going home finally. Going to be
researching todays topics tonight and over the weekend for some work I
am about to start.
The topics I need to cover are doing some calculations with a DSO over
subdivision surfaces on user selected points. I have done similar
things before, however this time the calculations we require are
inverse of the normal render pipeline. Sort of a chicken before the
egg problem with procedurals.
